It's a surprisingly common scenario: a user creates a draft message and forwards it to a coworker or manager for approval or additional comments. The message is then supposed to be sent. Except, it can't be sent because the Send button is grayed and disabled.
There is no Send button because Outlook doesn't see it as a draft message, it sees it as an attached file.
The solution is about as easy as they come: drag the draft copy from the message to the Drafts folder. The Send button will be enabled when you open it from Drafts.
